Abstract: An apparatus (10, 10?) and a machine (100) for reforming a portion of a plastic package (50) using induction heating. The apparatus and machine comprise a frame (20) engaging the plastic package and a workpiece support (40) having an electrically conducting workpiece (44, 48, 102). An induction workhead (62) provides an alternating current power supply to an induction element (60, 104). The induction element is positioned proximate the workpiece of the workpiece support and heats the workpiece via induction. A mechanism (22) positions the plastic package proximate the heated workpiece so that the workpiece transfers heat to the portion of the plastic package thereby softening the portion. A forming die (30) supported on the frame engages the portion to reform the portion. Also provided is a process of using the apparatus and machine to reform a portion of a plastic package using induction heating.

Abstract: An apparatus, mounted to a mold, for injecting air into a mold cavity and removing exhaust from the mold cavity, comprising: a blow cylinder body block mounted to the mold having a conduit to the mold cavity, wherein the blow cylinder body block comprises an insulator and the conduit has walls; a needle passing through the blow cylinder body block and the conduit, wherein the needle is connected to a piston, wherein the needle has a needle passage, and wherein compressed air is applied to the piston to extend the needle into the mold cavity and retract the needle from the mold cavity; and an insulator between the needle and the conduit walls.
